Laboratory animals are animals used in scientific research to help scientists understand biological processes, test new drugs, and study diseases. Common laboratory animals include mice, rats, rabbits, and monkeys. These animals are chosen for their genetic similarities to humans or their ability to reproduce quickly, making them ideal for experiments. The use of laboratory animals is regulated to ensure their welfare and minimize suffering. Researchers follow strict guidelines to provide proper care, housing, and handling. The goal is to obtain reliable results while respecting the ethical treatment of these animals in the pursuit of scientific knowledge.
